NAIL-PLATE FEEDER. Y

Specification forming part of Letters Patent No. 17,278, dated May 12, 1857; Ressued July 10, 1866, No. 2,301.

To all whom t may concern i Be it known that I, Jol-IN C. GOULD, of Boonton, in the county of Morris and State of New Jersey, have invented a new and Improved Mode of Feeding Nail-Machines;

and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon, like letters designating like parts, in which- Figure 1 is a side elevation. Fig. 2 is a c plan view. Fig. 3 isV an end view.

The nature of my invention consists in the manner of feeding the material to the cutters as hereinafter described.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction, and operat-ion.

In Fig. l, A is the spindle, to which a pulley can be attached, for applying the power; B the fly wheel; C gear wheel on the spindle; D, gear wheel on shaft, for operating pitman E;'F, the crank, or arm with socket, in which is a rod with a ball on it, and which connects it t0 t-he pitman allowing the pitman .to have a lateral, as well as a vertical motion; G, the crank shaft, for operating the ratchet cam, which operates the nose piece, and which is fastened` on two centers as shown in Fig. 3 letters (7b) H the frame of the nail machine; K, the cutter blocks, in which the knives are placed; L, the bearing for the end of the rock shaft; M the rock shaft; N attached arm to the shaft M, with a set screw b, for pressing against the supporting rod on which the revolving tube rests; O, the supporting rod; P the journal box, which is composed of two pieces to the lower one of which, is a lip, that serves to guide the rod, in entering the nose piece; R the arm for supporting the rod, holding the material to be out; S slotted arm into which the rod falls and by which it is fed up, one of the arms is a spring which serves to grip the rod and press it forward to the cutters, but, as the rod turns it is relieved from the grasp of the arm, and does not draw back; T, the rod for giving reciprocating motion to the arm S; c, a rest for stopping the arm in its forward motion causing it to feed regularly; U the nose piece, (on which is ratchet wheel, cZ,) which turns in the journal boxes P; V

` the feeding rod; V', connecting rod, giving the forward, and backward motion to the feeding apparatus, and is attached t0 the main spindle, on which is an eccentric cam, around which itis fastened by means of a collar, in the end of the rodnext the journal box, where it is attached. There is a spring V2 which yields, and allows the nose piece to always keep in proper position, and answers for small nails, but I do not confine myself to this device, for making large nails I may lind it better to use a pitman.

In Fig. 2, I do not deem it necessary in this, and the vnext ligure, to designate the nail machine, V' is the connecting'rod, attached to main spindle A; V the feed rod; (d), the ratchet wheel; U, the nose piece; j, guide; S, slotted arm; F', ratchet cam; M the rock shaft; P, the journal box; (b), the set screw for pressing laterally the rear end of the nose piece to change the :size of the head; c' crank on the shaft of gear wheel D; E, pitman. Y Y In Fig. 3, M the rock shaft; L, the bearings of the rock shaft; F' ratchet cam; N, arm attached to the shaft through which passes set screw o; S slotted arm, the left side of which is a spring attached by screw f; V the feed rod; U, the nose piece; P the journal boxes; g, screw for fastening them together; Y the arm on crank shaft G, having two centers at L, for the purpose of giving a forward and backward motion to the ratchet cam as it moves vertically.

In the operation of my invention power is applied to a pulley on the end of spindle A, which puts in motion gear wheel D, which imparts motion to shaft g, by means of pitman E. As the shaft g oscillates, it causes the arm y, seen in Fig. 3, to vibrate which gives to cam F', a vertical motion, it also having two centers (7L) (It) allows the ratchet cam F', to have a forward and backward motion, thus allowing it to accommodate itself, to the motion of the nose piece By means of the eccentric cam, on the spindle, with a collar clamping it, the connecting rod V', is put in motion. This rod reciprocates, and being connected to the journal box, it gives to the whole feeding arrangement a reciprocating movement. By this means I get the semirotating m0- tion of the nose piece, and its backward, and forward motion. When I charge the feed rod with the material to be used, it is inserted into the tube or hollow nose piece;

I motion of the nose piece.

and therear end is let rest in the slotted arm. It will be seen that the end of the feed rod resting in the armis flat, so that as it rotates by the turning of the nose piece, it will be alternately grasped by the arm, and pushed forward to feed; then let lose, and the arm slid back without clasping it. This motion is given to the arm by means of the rod F, which is attached to the arm, and extends back to meet the machine; and as the apparatus is moved forward the rod y comes in cont-act with the machine and pushes forward the lower end of arni s (it being hung on a center), causing the upper end to move forward, and push the feed rod up to the cutters. A spring (as) in its front, throws it back to a vertical position. As the nose piece revolves, there is a pin, or stationary plate la, on the journal box, for the purpose of regulating the semirotary I have placed guide J, on the side of the nose piece, where the nail. head is, which causes a uniformity in the heading, for if the plate is a fraction. wider than at other points, the head end rests against the guide, and presses open the spring on the other side, and so when the nose piece is rotated, the spring will open on the other side. When I wish to remove the knives, I have only to unscrew the connecting rod from its connection with the journal boX, and then I can turn the whole feeding apparatus over out of the way, so

that the knives are easily taken out, or v replaced. In supplying the machine with the material to be cut into nails, I only have to lift out the feed rod, and instantly insert another already charged, which is a great saving of time in supplying the Inaterial to the machine.

Having thus fully described the construction and operation of my invention, what I claim as new, and desire to secure by Letters Patent is- 1. The feed rod V, the forked spring arm S in combination with the feed rod 'I operating as described, and for the purpose set forth.

2. I claim placing the ratchet cam F', on arm Y, -for allowing it to have a forward and backward motion, also a vibratin motion, for the purpose of accornmo ating itself to the movement of the nose piece, and for revolving the same as herein described and set forth.

3. I claim arranging the feed apparatus as described, by which I can readily adjust the same, for the purpose of changing the cutters as set forth.
